What is the service temperature limit for Glass Fibre insulation?

The service temperature limit for Glass Fibre insulation is indeed 454°C (850°F). This temperature range is significant for applications where thermal stability is required, as glass fibre insulation can effectively maintain its insulating properties and structural integrity up to this limit. Glass fibre is known for its excellent resistance to heat and thermal shock, which makes it suitable for high-temperature insulation applications, such as in industrial furnaces, kilns, and equipment in power generation settings.

Materials like glass fibre have a unique composition that allows them to withstand elevated temperatures compared to many organic insulations, which may degrade or lose their insulating properties at lower temperatures. In practice, staying within the service temperature limit for such materials prevents failure and ensures safety and efficiency in thermal systems. This aspect is crucial for operators and engineers when selecting insulation materials for environments exposed to high heat.
